Application filed July 12. 1917, Serial No. 180.210.

. 7'0 all whom it In 113 concern lie it known that I, GEORGE (li F. Bos- WELL, a citizen of the United States, and a resident. of Indianapolis, county of Marion.

and State of Indiana, have invented a-certain new and useful Shock-Absorber; and

1 do hereby declare that. the following is a tall, clear. and exactdescription thereof, reference being had to the accompanying drawings. in which like. letters refer to like v parts.

. mlhereot'.

My invention relates to new and useful improvements in a combined shock absorber and cushioning means for vehicles and is more particularly adapted for use in connection with a-Ford automobile wherein a scmielliptie spring is used.

My object is to provide a spring const ruction and attach the same to the springs andsupporting brackets therel'or. in such a manner that the mechanism will coopcrate with the spring and give the same ctfect to the spring as when a tall elliptic spring is used.'

, further object. is to so construct the device that it can be readily attached to the t'orm' of springs and brackets as now painut'ac'tiired without changing any ot'the parts further object is to so construct. the device that the body of the car will be held against vibration or lateral swinging movement. when the car is at rest and the engine is running...

A further object is to so construct the device that the endwise thrust. of the body springs will be. cushioned in either direction.

further object is to so construct the device that any shock delivered to the wheels of the vehicle will be practically absorbed before being transmitted to the body ol the 'car. i

()thcr objects and :ulvantages will be hereinafter more fully set forth and pointed out in the accompanying specification.

The tall nature of the invention will be understood from the accompanying drawing and the following description and claims:

Figure 1 is an elevation of tho frontaxle of an automobile showing my improved device attached thereto. Fig. 2 is an enlarged elevation of one end of one body spring "amta supporting bracket. therefor. showing my improved device in its normal position. Fig. 3 is a vertical sectional vimvthrough the shock absorbing device. and the hanger connecting the body spring to the bracket. Fig. 4 is a View similar to Fig. 2 showing the position of the parts when the spring of the vehicle is.tle.\'cd.

1 indicates the axle of the vehicle. which in this instance. is the front axle of a Ford automobile. said axle having the usual form of brackets :2 attached thereto from which are suspended the ends of a spring 3 by means of the links -t and bolts 5 and 6, which parts are of the usual or well known construction.

in order to cushion any blow delivered to the wheels 7 of the vehicle and toregulate the endwise thrust of the spring 3, I provide a cushioning spring 8 which is substantially circular in form, one end of said spring being attached to the bracket '2 in any preferred manner. as by means of the coupling 9 which extcnds below.the bracket '3 and through a clip 10 extending over the end of the cushioning spring 8. the ends of the coupling 9 being threaded to receive nuts ll by means of whi the clip is clamped on to the end of the cushioning spring and said 1 eml held in firm engagement with the.

bracket.

The opposite end of the cushioning sprin h is bent into the "form of an eye 1'2. througii which extends a bolt 13. said bolt being in turn introduced through the cars It (if a cleris 15. which clevis is intrm'tuccd around the end of the body spring 3 in close proximity to the. loop 16 'at the end ot' the body spring in order to hold the couplin against movement longitudimllly of the ody spring than anchoring tongue 17 is attached to the coupling 15 and preferably formed anchoring tongue integral therewith. said being curved to fit the contour of the loop 16 so that when the coupling 15 is properly positioned upon the body spring 3, said anchorin ton ue will en agethe loo) ti L I F i I and partially surround the same. The eye 12 of the cushioning spring is so constructed that itv will rest upon the upper t'ace' ot the body spring, when the; same is positioned between the ears 14 and engaged by the bolt 14, and the coupling will be securely held against movement independently'of the body spring.

' The cushioning spring 8 preferably con structed of a fiat piece of of a uniform width but preferably, tapered in thickness 1 from the end anchored to the bracket to the end engeged vvith the body spring and as [said cushioning-"s eving is suhstcntmllyicir-I solar in iiornneny abrupt bonds or curve- ,tnres, which might cause crystellizstion of the cnsiiioningspring, will be entirely elimi- By constructing the cushioning spring in manner shown and positioning the some irectly over the. connecting point between "the body spring of the jvehiclennd its sn' fportinghrscket, any movement of the-ho y "spring will be readily regulated end enynndue znonement of the axle of the vehicleend iverdly on the body springs spring is given. an end vi sequence of this act-ion,

suppoirting' bracket, when n blow is 'deliiered tothefn heei ofthe vehicle, was he precticelly entirely absorbed or sssimllisted by the cushloningspring before it is transmitted to the body spring.

i It will further be seon thet in View of the cin curler construction of the cushioning spring, said spring will have a tendency to lift up when said body iri stend in concbody incident to thoviorstion of the motel,
